Abstract

Since 1974, the preparation of polymeric fibers and films with high strength and high modulus has been extensively investigated for flexible polymers by gel-state spinning(1), ultradrawing of dried gel films(2), ultradrawing of single crystal mats(3), and two-step drawing of single crystal mats(4). Recently, Matsuo et al. using the method of Smith and Lemstra(2) produced ultradrawn polyethylene(5) and polypropylene(6) whose Young’s modulus at 20°C was 216 and 40.4 GPa, respectively. These values were nearly equal to the crystal lattice moduli of polyethylene(5) and polypropylene(7) as measured by the X-ray diffraction technique.
